What is this?
A docker image with rTorrent and the Flood UI, also optional WireGuard VPN support.
Starting the container¶
docker run --rm \ --name rflood \ -p 3000:3000 \ -e PUID=1000 \ -e PGID=1000 \ -e UMASK=002 \ -e TZ="Etc/UTC" \ -e FLOOD_AUTH="false" \ -v /<host_folder_config>:/config \ hotio/rflood
version: "3.7" services: rflood: container_name: rflood image: hotio/rflood ports: - "3000:3000" environment: - PUID=1000 - PGID=1000 - UMASK=002 - TZ=Etc/UTC - FLOOD_AUTH=false volumes: - /<host_folder_config>:/config
docker run --rm \ --name rflood \ -p 3000:3000 \ -p 8118:8118 \ -e PUID=1000 \ -e PGID=1000 \ -e UMASK=002 \ -e TZ="Etc/UTC" \ -e VPN_ENABLED="true" \ -e VPN_LAN_NETWORK="" \ -e VPN_CONF="wg0" \ -e VPN_ADDITIONAL_PORTS="" \ -e PRIVOXY_ENABLED="false" \ -e FLOOD_AUTH="false" \ -v /<host_folder_config>:/config \ --cap-add=NET_ADMIN \ --sysctl="net.ipv4.conf.all.src_valid_mark=1" \ --sysctl="net.ipv6.conf.all.disable_ipv6=0" \ hotio/rflood
version: "3.7" services: rflood: container_name: rflood image: hotio/rflood ports: - "3000:3000" - "8118:8118" environment: - PUID=1000 - PGID=1000 - UMASK=002 - TZ=Etc/UTC - VPN_ENABLED=true - VPN_LAN_NETWORK - VPN_CONF=wg0 - VPN_ADDITIONAL_PORTS - PRIVOXY_ENABLED=false - FLOOD_AUTH=false volumes: - /<host_folder_config>:/config cap_add: - NET_ADMIN sysctls: - net.ipv4.conf.all.src_valid_mark=1 - net.ipv6.conf.all.disable_ipv6=0
In most cases you'll need to add additional volumes, depending on your own personal preference, to get access to your files.
WireGuard VPN support¶
This is probably not going to work if your OS has no kernel with WireGuard support.
Tested Operating Systems:
- Ubuntu 18.04
- Ubuntu 20.04
- Unraid 6.8.3
- Unraid 6.9 RC2
- macOS Big Sur 11.2.1 Apple M1
There needs to be a file
wg0.conf located in
/config/wireguard and you need to set the variable
true for the VPN to start.
The part with
net.ipv6.conf.all.disable_ipv6=0 can be removed or set to
1 if there is no need for ipv6, no attempt will be made in that case to set ip6tables rules and can prevent an error if the module
ip6table_filter isn't loaded on the host. The WireGuard configuration should not have any ipv6 related stuff when ipv6 is disabled, otherwise creating the interface will fail. If your vpn provider supports ipv6 and you keep it enabled, you'll have full ipv6 connectivity over the vpn connection (confirmed with Mullvad). If for any reason there's a failure trying to setup ip6tables rules, you'll probably need to do
sudo modprobe ip6table_filter on the host, this will mostly happen on systems that have ipv6 completely disabled.
The environment variable
VPN_LAN_NETWORK can be set to for example
192.168.1.33, so you can get access to the webui or other additional ports (see below).
If you need to expose additional ports you can use
VPN_ADDITIONAL_PORTS, for example
VPN_ADDITIONAL_PORTS=7878/tcp,9117/tcp. Every port in this list will be blocked on the vpn interface, so that there's no risk that they might be exposed to the world via the vpn (mostly there in case your vpn provider screws up and piece of mind). Why would you need this? Wanting to route traffic from other containers over the vpn is probably the most used scenario.
This is an example of how your
wg0.conf could look like.
[Interface] PrivateKey = supersecretprivatekey Address = xx.xx.xxx.xxx/32 DNS = 188.8.131.52 [Peer] PublicKey = publickey AllowedIPs = 0.0.0.0/0 Endpoint = xxx.x.xxx.x:51820
While Mullvad is pretty straightforward to setup by using the
wg0.conf example from above, TorGuard is a bit more complex.
wg0.conf should look something like this:
# TorGuard WireGuard Config [Interface] PrivateKey = secretprivatekey ListenPort = 51820 DNS = 184.108.40.206 Address = xx.xx.xxx.xx/24 PreUp = bash /config/wireguard/torguard.sh [Peer] PublicKey = publickey AllowedIPs = 0.0.0.0/0 Endpoint = xx.xxx.xx.xxx:1443 PersistentKeepalive = 25
Pay attention to
PreUp = bash /config/wireguard/torguard.sh in our config. That command will execute the below script that you should create in
/config/wireguard/torguard.sh, this script will get executed just before starting WireGuard.
1 2 3 4 5 6 7
You will also have to add the additional environment variables
TORGUARD_PASS or fill them in into the script directly (see
curl command). These credentials can be found here.
My experience with getting TorGuard working wasn't the smoothest journey to say the least. I had to click around quite a bit and finally after generating my 3rd config it worked. On the
Netherlands server for example I didn't get any internet connectivity and at first I was unable to get port forwarding working on the
Germany server. All of a sudden after generating the 3rd config and also pasting in the ip found under
My Fixed IPs, that seems to populate when doing a Port Forward Request, I managed to get port forwarding working. So don't give up too soon, it can all work eventually.
